Ok im getting a misfire cel 74. My car drive and ifles normal. I have no idea what is causing this cel. I have changed distributor cap and switched to another working dirstirbutor. I have changed new spark plugs and new spark plug wires.
I swapped around the injectors and still i get this CEL!!! When im using the obd1 ecu, i get no cel. Its only when i run the obd2 ecu.

Oh yeah, all this happened after i was boosted and when back to stock. When i went back to stock, i used my old obd2 p72 and thats when i got the cel.

Someone help me out, i want to resolve this issue so i can boost again and get tuned..

 

bump.

 

my itr had this problem before boost. It was the factory coil. I replaced it with a Jacobs set-up and it works fine. Good luck
